Effective compensation while also masking muzzle flash has always been a tall order for a muzzle device. The Enhanced Flash Arresting Brake from Precision Armament has improved upon the AFAB in both of those roles with a uniquely designed complex of internal passageways that diffuse and cool the propellant gasses and mitigate muzzle flash, while also directing those gasses in such a way as to keep your muzzle flat in rapid fire strings on barrels as short as 10". Designed for battlefield performance, the EFAB also features a fully closed bottom to also minimize dust signature when firing from the prone position.

Note:Manufacturer warns users to not utilize crush washers for installation of this muzzle brake.

Best Muzzle Device for Unsuppressed use

by -

Really impressed with this muzzle device. Wanted a device that provided decent compensation and recoil reduction, along with acceptable flash suppression, and the EFAB delivered. The compensation and recoil reduction are perfect, it gives off minimal concussion and blast, and to top it all off, the flash suppression is noticeably better than an A2 birdcage. If you don't need QD suppressor capability, really hard to beat this option.
